SAF1 Open Fail
Safety Relay SAF1 Failed to Open
Causes
The controller is trying to de-energize (open) safety relay SF1 but the feedback from the relay
shows that it is still energized (closed).
Output 601 on the Machine Room SRU board controls the coil of the relay. Input 520 is the
normally closed feedback monitor.
When 601 is off, 520 should be on. If 520 reports the wrong state for more than 1 second then
this fault is logged.
Remedies
Check to see if the SF1 relay is properly seated in the socket and does not have any bent pins.
Check Jumper J19 (Rev 5-7 SRU) and J24 (Rev 8 SRU) for proper configuration. Refer to
provided drawings.
Check MAIN MENU | STATUS | IO | INPUT GROUPS | CONTROLLER | SAF1 to see if the status
is changing with Output 601.
Check wiring for 601 / 520.

Remedies
Check the SF2 relay. Verify it is properly seated in the socket and does not have any bent pins.
Check Jumper J19 (Rev 5-7 SRU) and J24 (Rev 8 SRU) for proper configuration. Refer to
provided drawings.
Check MAIN MENU | STATUS | IO | INPUT GROUPS | CONTROLLER | SAF2 to see if the status
is changing with Output 601.
Check wiring for 601 / 526.
